Panel Under CD player 03 Civic

Yo,

Im "trying" to replace that storage box underneath my cd player in my 03 civic and put in a fiber glass gauge pod I made for it. But Unsuccesfully have I been at trying to get the sob out of there. I can't find any screw holes or bolt holes to remove it, I can however pull it about a 1/4 of an inch out by hand so its not in there very tight. Any help is appreciated.

Thanks
